Ingroups of 3-4 students, think carefully about what happens when we continue to add more and more people to the planet. Brainstorm and discuss the impacts that more people have, for better or for worse. In some cases, adding more people will cause there to be more of some things which causes more of other other things in a chain reaction. In other cases, more of some things might cause less of others in a chain reaction. Use the attached graphic organizer to document your ideas and discussion. Example: Adding more people causes us to need to build more houses which means we need to cut down more trees for lumber which results in more clearcutting of forests and less trees which reduces the amount of oxygen being produced on the planet.
